Description

Technical Field

[0001] This application relates to the field of computing device technology, and in particular to a computing device and a rack server. Background Technology

[0002] With the development of big data, cloud computing, and artificial intelligence (AI), the frequency of installing and debugging computing devices is increasing. Computing devices need to be frequently installed in or removed from rack servers.

[0003] A wrench can be used to mount or unmount computing devices. The wrench has a first end and a second end. The first end is for the operator to grip, and the second end is rotatably connected to the computing device. The second end of the wrench has a slot, and the server rack has a protrusion that engages with the slot. When the operator applies force to the first end, it drives the second end to rotate, with the second end traveling along the depth of the rack. The protrusion also applies force to the slot, and the combined travel of the second end along the rack's depth and the force exerted by the protrusion on the slot allows the computing device to be pushed into the rack, facilitating the insertion of the first interface on the computing device into the second connector on the rack. The insertion and extraction of the first and second interfaces requires significant force and travel.

[0004] In related technologies, the force and stroke provided by the wrench are relatively small, making it difficult to meet the insertion requirements of the first and second connectors. Summary of the Invention

[0005] This application provides a computing device in which the plug-in mechanism can provide a large force and stroke.

[0006] In a first aspect, embodiments of this application provide a computing device, including: a housing, a plug-in mechanism, and a first interface. The first interface and the plug-in mechanism are disposed on opposite sides of the housing along a first direction. The first interface is used to plug into a second interface inside a cabinet. The plug-in mechanism includes: a handle and a movable component. The handle includes a first end and a second end. The second end is rotatably connected to the housing and has an arc-shaped portion. The movable component has an elongated portion on the side facing the arc-shaped portion. The arc-shaped portion and the elongated portion are drively connected. The elongated portion extends along the first direction. The movable component has a first protrusion on the side away from the elongated portion. The first protrusion is used to abut against the first surface of the second protrusion on the cabinet. When the first end of the handle rotates away from the housing, the arc-shaped portion drives the elongated portion to move relative to the cabinet along the first direction, thereby driving the computing device to move away from the cabinet along the first direction.

[0007] The computing device provided in this application embodiment has an arc-shaped portion on the handle and an elongated portion on the moving part. The rotation of the arc-shaped portion drives the elongated portion to move along a first direction, so that the entire arc length of the arc-shaped portion is converted into the stroke of the elongated portion along the first direction. The computing device can have a large stroke relative to the cabinet along the first direction, which can meet the required movement of the computing device relative to the cabinet when the first and second interfaces are disconnected. The radius of the arc-shaped portion can be small, resulting in a large force-saving ratio coefficient. Therefore, the first force exerted by the second protrusion on the first protrusion can be large, which can meet the insertion requirements of the first and second interfaces.

[0008] In one possible implementation, the computing device provided in this application embodiment has an arc-shaped portion that is a gear and a long strip portion that is a rack. The gear and rack mesh to convert the rotation of the gear into the movement of a moving part along a first direction. Through the cooperation of the gear and rack, the rotation of the arc-shaped portion can be converted into the movement of the long strip portion along the first direction. The structure of the gear and rack is simple and can effectively transmit force.

[0009] In one possible implementation, the computing device provided in this application embodiment further includes a third protrusion in the plug-in / plug-out mechanism. The third protrusion is disposed on the side of the moving member away from the elongated portion. The third protrusion and the first protrusion are spaced apart along a first direction. The third protrusion is used to abut against the second surface of the second protrusion on the cabinet. When the first end of the handle rotates toward the housing, the arc-shaped portion drives the elongated portion to move relative to the cabinet along the first direction, thereby driving the computing device to move toward the cabinet along the first direction. By providing the third protrusion and applying a second force during the mounting process of the computing device through the abutment between the third protrusion and the second surface of the second protrusion, the protrusion interacting with the cabinet during the mounting process and the protrusion interacting with the cabinet during the unmounting process can be separated. This avoids the back-and-forth movement of a protrusion between the first and second surfaces of the second protrusion to accommodate both mounting and unmounting processes.

[0010] In one possible implementation, the computing device provided in this application embodiment has a first opening extending through a second direction on a movable member, and a third protrusion aligned with the first opening along the second direction. The third protrusion is movable relative to the first opening along the second direction. When the computing device is mounted, the third protrusion extends from the first opening to protrude from the side of the movable member opposite to the elongated portion. When the computing device is removed from the mounting, the third protrusion retracts relative to the first opening to at least be flush with the side of the movable member opposite to the elongated portion. This avoids interference between the second and third protrusions, allowing the computing device to be removed smoothly.

[0011] In one possible implementation, the computing device provided in this application embodiment further includes a slider in the plug-in / plug-out mechanism. A third protrusion is connected to the slider, and the slider is movable relative to a moving member in an inclined direction, the inclined direction being inclined relative to a first direction and a second direction. The sliding length of the slider along the inclined direction has a length component along the second direction, thereby allowing the third protrusion to move in the second direction simultaneously with the slider moving in the inclined direction.

[0012] In one possible implementation, the computing device provided in this application embodiment includes a base for the plug-in / plug-out mechanism. The base is fixedly connected to the housing, and the second end of the handle is rotatably connected to the base. Both the gear and the slider are located within the base. The base has a first slide rail extending in an inclined direction, and the slider has a first groove on its side facing the base, which engages with the first slide rail. The base allows the plug-in / plug-out mechanism to form a compact module, facilitating connection between the mechanism and the housing. The first groove and the first slide rail form a limiting structure, allowing the slider to move relative to the base in an inclined direction.

[0013] In one possible implementation, the computing device provided in this application embodiment further includes a top cover on a base. The top cover has a second slide rail extending in an inclined direction. The side of the slider facing the top cover has a second groove that engages with the second slide rail. By providing structures on both sides of the slider in the third direction to restrict its movement in the inclined direction, the failure of the restricting structure on one side can be prevented from altering the slider's movement path.

[0014] In one possible implementation, the computing device provided in this application embodiment has a first connecting portion on the slider and a second connecting portion on the side of the moving member facing the slider. The first connecting portion is connected to the second connecting portion, and the first connecting portion is movable relative to the second connecting portion in a second direction, so that when the third protrusion moves relative to the moving member in the second direction, the slider moves relative to the moving member in an inclined direction. By moving the first connecting portion relative to the second connecting portion in the second direction, the slider can move relative to the moving member in the second direction while moving in the inclined direction.

[0015] In one possible implementation, the computing device provided in this application embodiment has one of the first connecting portion and the second connecting portion as a socket extending along a second direction, and the other as a column extending along the second direction. The column is inserted into the socket with a clearance fit. Inserting the column into the socket simplifies the connection between the moving member and the slider. The clearance fit between the column and the socket reduces the resistance to the slider's movement relative to the moving member along the second direction.

[0016] In one possible implementation, the computing device provided in this application embodiment includes an elastic element in its insertion / removal mechanism. A partition is located within the base, with a gear and a slider positioned on opposite sides of the partition. One end of the elastic element abuts against the partition, and the other end abuts against the slider. Under the elastic force of the elastic element, the distance between the slider and the partition is maximized. Consequently, the third protrusion connected to the slider remains flush with the side of the moving member opposite to the elongated portion. Therefore, interference between the third protrusion and the second protrusion can be avoided during the insertion or removal of the computing device from the cabinet.

[0017] Secondly, embodiments of this application provide a rack-mount server, including a rack and a computing device. The computing device includes: a housing, a plug-in mechanism, and a first interface. The first interface and the plug-in mechanism are disposed on opposite sides of the housing along a first direction. The first interface is used to plug into a second interface inside the rack. The plug-in mechanism includes:

[0018] The handle includes a first end and a second end, the second end being rotatably connected to the housing, and an arc-shaped portion is provided on the second end;

[0019] The movable part has a long strip on the side facing the arc-shaped part, the arc-shaped part and the long strip are connected in a transmission manner, the long strip extends along a first direction, and the movable part has a first protrusion on the side away from the long strip, the first protrusion is used to abut against the first surface of the second protrusion on the cabinet.

[0020] When the first end of the handle rotates away from the housing, the arc-shaped part drives the long strip to move relative to the cabinet in a first direction, thereby driving the computing device to move away from the cabinet in the first direction. Attached Figure Description

[0076] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0077] With the development of big data, cloud computing and AI, the frequency of installing and debugging computing devices is increasing. Computing devices need to be frequently put into or taken out of the rack server cabinet.

[0078] Figure 1This is a schematic diagram of the structure of a data center provided in an embodiment of this application.

[0079] See Figure 1 As shown, data center 1000 is a facility for installing computing equipment and related components, such as telecommunications and storage systems. The data center 1000 provided in this embodiment may include at least one server. The server may be located within computer room 20.

[0080] Data center 20 can be configured with one or more servers. When multiple servers are configured in data center 20, the servers can be identical, partially identical, or all different. Servers can be various types, such as desktop servers, blade servers, rack servers, high-density servers, and full-rack servers.

[0081] Rack servers are widely used in fields such as cloud computing, high-performance computing (HPC), big data, and artificial intelligence due to their high space utilization.

[0082] The following section uses a rack-mount server as an example to illustrate the structure of computing devices.

[0083] Figure 2 This is a schematic diagram of the rack server provided in an embodiment of this application.

[0084] See Figure 2 As shown, the rack server 10 includes a rack 200 and multiple computing devices 100 disposed within the rack 200. The rack 200 is typically a cuboid, with its depth direction being the first direction X, its width direction being the second direction Y, and its height direction being the third direction Z. The multiple computing devices 100 are arranged along the third direction Z within the rack 200.

[0085] The process of inserting the computing device 100 into the cabinet 200 is called the loading process of the computing device 100. The process of removing the computing device 100 from the cabinet 200 is called the unloading process of the computing device 100.

[0086] Figure 3 A schematic diagram of the structure of a computing device provided in an embodiment of this application.

[0087] See Figure 3 As shown, the computing device 100 includes a housing 110, which may also be a cuboid structure. The length direction of the housing 110 is the first direction X, the width direction of the housing 110 is the second direction Y, and the thickness direction of the housing 110 is the third direction Z.

[0088] Figure 4 This is a schematic diagram of the internal structure of a computing device provided in an embodiment of this application.

[0089] See Figure 3 and Figure 4 As shown, the computing device 100 also includes a plug-in mechanism 120. The housing 110 includes a front side 110a and a rear side 110b opposite to each other along a first direction X. The plug-in mechanism 120 is disposed on the front side 110a. The plug-in mechanisms 120 are arranged in pairs on the housing 110 along a second direction Y.

[0090] The computing device 100 also includes a plurality of first interfaces 130, which are disposed on the rear side 110b. That is, the first interfaces 130 and the plug-in mechanism 120 are disposed on opposite sides of the housing 110 along the first direction X. The first interface 130 can be a liquid cooling interface or a connector interface.

[0091] Figure 5 This is a schematic diagram illustrating the installation of computing devices and the cabinet in a rack server provided in an embodiment of this application.

[0092] See Figure 2 and Figure 5 As shown, the cabinet 200 includes a front panel 210 and a rear panel 220 disposed opposite to each other along a first direction X. When the computing device 100 is installed inside the cabinet 200, the front side 110a of the housing 110 of the computing device 100 faces the front panel 210, and the rear side 110b of the housing 110 of the computing device 100 faces the rear panel 220. The front panel 210 can be used as a cabinet door, and the front panel 210 can be opened to allow the computing device 100 to be placed on or removed from the cabinet.

[0093] The second interface 221 can be located on one side of the rear panel 220. In one possible embodiment, the cabinet 200 has a back panel, which is located close to the rear panel 220. The second interface 221 can be a liquid cooling interface or a connector interface located on the back panel. In another possible embodiment, the second interface 221 can be an interface that connects to an external power supply or other rack server 10 via a cable. The following description will use the example of the second interface 221 being located on the back panel of the cabinet 200.

[0094] The second interface 221 is plugged into the first interface 130 in a one-to-one correspondence. A relatively large insertion force is required when the first interface 130 is plugged into or disconnected from the second interface 221. The cabinet 200 also includes two side panels 230 opposite each other along the second direction X. A plugging / unplugging mechanism 120 can apply force to the computing device 100 and the side panels 230. The force on the computing device 100 is transmitted to the first interface 130, and the force on the side panels 230 is transmitted to the second interface 221, facilitating the plugging or unplugging of the first interface 130 and the second interface 221.

Figure 1 ; Figure 9b A schematic diagram illustrating the process of removing the computing device from the cabinet according to an embodiment of this application. Figure 2 ; Figure 9c A schematic diagram illustrating the process of removing the computing device from the cabinet according to an embodiment of this application. Figure 3 .in Figures 7 to 9c All diagrams show partial structural schematics of the computing device 100 to clearly illustrate the structure of the plug-in mechanism and the housing. Figure 8 The casing of the computing device is omitted in the Chinese version.

[0096] See Figures 6 to 9a As shown, the plug-in / plug-out mechanism 120 includes a handle 121 and a moving member 122. The handle 121 includes a first end 121a and a second end 121b. The second end 121b is rotatably connected to the housing 110 and has an arc-shaped portion 1211. The moving member 122 has an elongated portion 1221 on the side facing the arc-shaped portion 1211. The elongated portion 1221 extends along the first direction X. The moving member 122 has a first protrusion 1222 on the side away from the elongated portion 1221. The first protrusion 1222 is used to abut against the first surface 2311 of the second protrusion 231 on the cabinet 200. When the first end 121a of the handle 121 rotates away from the housing 110, the arc-shaped portion 1211 drives the elongated portion 1221 to move relative to the cabinet 200 along the first direction X, thereby driving the computing device 100 to move away from the cabinet 200 along the first direction X.

[0097] For details, please continue reading. Figures 6 to 8As shown, the housing 110 includes a bottom wall 111 and a side wall 112. A plug-in / plug-out mechanism 120 is disposed at the connection between the bottom wall 111 and the side wall 112. The handle 121 of the plug-in / plug-out mechanism 120 can be elongated, including a first end 121a and a second end 121b opposite to each other along its extension direction. A pivot 1111 is provided on the bottom wall 111. The second end 121b of the handle 121 is inserted into the pivot 1111, allowing the handle 121 to be rotatably connected to the bottom wall 111 of the housing 110. When an operator grips the first end 121a of the handle 121 and applies force to it, the force is transmitted to the second end 121b, allowing the second end 121b to rotate relative to the housing 110. The second end 121b can be a circular structure centered on the pivot, with the arcuate portion 1211 being part of this circular structure.

[0098] The movable member 122 is an elongated member extending along the first direction X. The movable member 122 can be fitted to the side wall 112 of the housing so that the side wall 112 of the housing can provide support for the movable member 122.

[0099] The elongated portion 1221 can be a lead screw, and the arc-shaped portion 1211 can be a turbine. When the turbine rotates, it can drive the lead screw to move along the first direction X. Please continue reading. Figure 7 and Figure 8 As shown, the arc-shaped portion 1211 can be a gear 1211a, and the elongated portion 1221 can be a rack 1221a. The gear 1211a meshes with the rack 1221a. When the gear 1211a rotates, it can drive the rack 1221a to move along the first direction X. The rack 1221a can then drive the moving member 122 to move along the first direction X. Through the cooperation of the gear 1211a and the rack 1221a, the rotation of the arc-shaped portion 1211 can be converted into the movement of the elongated portion 1221 along the first direction X. The structure of the gear 1211a and the rack 1221a is simple and can effectively transmit force.

[0100] The movable member 122 has a first protrusion 1222 on the side opposite to the elongated portion 1221, and the first protrusion 1222 moves with the movement of the movable member 122. It should be noted that the housing sidewall 112 of the housing 110 has an elongated hole 1121 extending in the first direction X, and the first protrusion 1222 extends out of the elongated hole 1121 so as to abut against the first surface 2311 of the second protrusion 231 on the cabinet 200. The first protrusion 1222 can also move in the elongated hole 1121 in the first direction X.

[0101] Please continue reading Figures 9a to 9c As shown, the side panel 230 of the cabinet 200 has a second protrusion 231, which includes a first surface 2311 and a second surface 2312 opposite to each other along the first direction X.

[0102] The following describes the process by which the insertion and removal mechanism 120 drives the computing device 100 to move along the first direction X so that the computing device 100 is removed from or mounted on the cabinet 200, taking the arc-shaped part 1211 as a gear 1211a and the long strip part 1221 as a rack 1221a as an example.

[0103] For details, please continue to see Figure 9a and Figure 9b As shown, the operator can hold the first end 121a of the handle 121 and rotate the handle 121 clockwise. The second end 121b of the handle 121 can rotate around the pivot 1111, causing the gear 1211a to rotate accordingly. The rack 1221a meshes with the gear 1211a. As the gear 1211a rotates clockwise, the rack 1221a can drive the moving part 122 to move along the first direction X toward the rear panel 220 of the cabinet 200. Figure 9a and Figure 9b The direction of rotation of gear 1211a is indicated by an arc with an arrow, and the direction of movement of moving member 122 is indicated by a straight line with an arrow.

[0104] The first protrusion 1222 also moves along the first direction X toward the rear panel 220 of the cabinet 200 with the moving part 122, so that the first protrusion 1222 abuts against the first surface 2311 of the second protrusion 231. Since the cabinet 200 remains stationary, the first surface 2311 of the second protrusion 231 can apply a first force F1 to the first protrusion 1222, so that the computing device 100 can move away from the rear panel 220 of the cabinet 200 until the first interface 130 on the computing device 100 is disconnected from the second interface 221 on the cabinet 200. Figure 9c After the first interface 130 and the second interface 221 are disconnected, the computing device 200 continues to move away from the cabinet 200 along the first direction X in order to be mounted or dismounted from the cabinet 200.

[0105] Figure 10 A schematic diagram of the travel path of a computing device provided in an embodiment of this application.

[0106] See Figure 10As shown, the arc length S of the gear 1211a rotating on the arc-shaped portion 1211 is the stroke H of the rack 1221a moving along the first direction X on the long strip portion 1221. In other words, the entire arc length S of the gear arc-shaped portion 1211 is converted into the stroke H of the long strip portion 1221 along the first direction X. Compared to the second end having a slot, where the stroke is the product of the radius of the second end and the sine of the degree of rotation of the second end, the computing device 100 can have a larger stroke H relative to the cabinet 200 along the first direction X. The stroke H can satisfy the value required for the computing device 100 to move relative to the cabinet 200 when the first interface 130 and the second interface 221 are disconnected.

[0107] The stroke H is equal to the arc length S, where S = (B / 360) * 2 * 3.14 * R. Here, B is the rotation angle B of the handle 121. Since the slot rotates with the second end, and the rotation angle of the second end cannot be too large in order for the slot to engage with the protrusion on the cabinet, this embodiment provides a mechanism through the cooperation of the arc-shaped portion 1211 and the elongated portion 1221. This prevents the first protrusion 1222 from rotating with the gear 1211a, thus preventing it from moving along the second direction Y. Consequently, the rotation angle B does not change the position of the first protrusion 1222 along the second direction Y, allowing the rotation angle B to be set larger, further increasing the arc length and thus increasing the stroke H.

[0108] Figure 11 This is a force diagram of a computing device provided in an embodiment of this application.

[0109] See Figure 11 As shown, the handle 121, the moving part 122, and the housing 110 form a lever structure. The pivot 1111 on the bottom wall 111 of the housing 110 is the fulcrum of the lever structure. The distance between the first end 121a of the handle 121 and the pivot 1111 is the first distance L0. The distance between the meshing point of the gear 1211a and the rack 1221a and the pivot 1111 is the radius R of the pitch circle of the gear 1211a. The force applied by the operator to the first end 121a is the operating force F0. According to the lever principle, the meshing force F between the gear 1211a and the rack 1221a and the operating force F0 satisfy the following formula:

[0110] F*R=F0*L0

[0111] Therefore, the operating force F0 can be calculated using the following formula:

[0112] F0 = F*R / L0.

[0113] The relationship between the indexing pressure angle A of gear 1211a, the first force F1, and the meshing force F can be expressed by formula three:

[0114] F1=F*cosA

[0115] The ratio between the operating force F0 applied by the operator and the first force F1 can be used to represent the force-saving ratio coefficient K of the operating mechanism 120, which can be expressed by the following formula:

[0116] K = F1 / F0

[0117] Substituting F0 from Formula 2 and F1 from Formula 3 into Formula 4, we obtain Formula 5 as follows:

[0118] K=F*cosA*L0 / F*R=L*cosA / R.

[0119] The pitch pressure angle A of the gear is a fixed value. For example, the pitch pressure angle A can be set to 20°. In this case,

[0120] K≈0.94*L0 / R

[0121] It is known that the smaller the radius R, the greater the force-saving ratio coefficient. In this embodiment, since the arc S of the arc portion 1211 can be completely converted into the stroke H of the computing device 100, the value of the radius R can be smaller, so that the force-saving ratio coefficient K is larger. Therefore, the first force F1 can be larger, which can meet the plugging requirements of the first interface 130 and the second interface 221.

[0122] The computing device 100 provided in this embodiment of the application has an arc-shaped portion 1211 on the handle 121 and an elongated portion 1221 on the moving member 122. The rotation of the arc-shaped portion 1211 drives the elongated portion 1221 to move along the first direction X, so that the entire arc length S of the arc-shaped portion 1211 is converted into a stroke H of the elongated portion 1221 along the first direction X. The computing device 100 can have a large stroke H relative to the cabinet 200 along the first direction X, and the stroke H can meet the required movement of the computing device 100 relative to the cabinet 200 when the first interface 130 and the second interface 221 are disconnected. The radius R of the arc-shaped portion 1211 can be small, resulting in a larger force-saving ratio coefficient K. Therefore, the first force F1 exerted by the second protrusion 231 on the first protrusion 1222 can be large, which can meet the insertion requirements of the first interface 130 and the second interface 221. Furthermore, the radius R of the arc-shaped portion 1211 is small, which makes the space occupied by the second end 121b of the handle 121 in the housing 110 along the first direction X and the second direction Y smaller, so that there is more space in the housing 110 to accommodate other components.

[0123] The process of mounting the computing device 100 into the cabinet 200 will be described below.

[0124] Figure 12This is another structural schematic diagram of the plug-in / plug-out mechanism in a computing device provided in an embodiment of this application; Figure 13a A schematic diagram illustrating the process of mounting the computing device from the cabinet according to an embodiment of this application. Figure 1 ; Figure 13b A schematic diagram illustrating the process of mounting the computing device from the cabinet according to an embodiment of this application. Figure 2 ; Figure 13c A schematic diagram illustrating the process of mounting the computing device from the cabinet according to an embodiment of this application. Figure 3 .

[0125] See Figure 12 and Figure 13c As shown, the plug-in mechanism 120 also includes a third protrusion 123. The third protrusion 123 is disposed on the side of the moving member 122 away from the elongated part 1221. The third protrusion 123 and the first protrusion 1222 are spaced apart along the first direction X. The third protrusion 122 is used to abut against the second surface 2312 of the second protrusion 231 on the cabinet 200. When the first end 121a of the handle 121 rotates toward the housing 110, the arc-shaped part 1211 drives the elongated part 1221 to move relative to the cabinet along the first direction Y, so as to drive the computing device 100 to move toward the cabinet 200 along the first direction X.

[0126] The third protrusion 123 is a protrusion that protrudes from the moving member 122 away from the elongated part 1221. The third protrusion 123 and the first protrusion 1222 can be disposed at both ends of the second protrusion 231 along the first direction X.

[0127] Please continue reading Figure 13a and Figure 13b As shown, when the computing device 100 is mounted in the cabinet 200, the operator holds the first end 121a of the handle 121, causing the handle 121 to rotate counterclockwise. The second end 121b of the handle 121 can rotate around the pivot 1111, causing the gear 1211a to rotate accordingly. The rack 1221a meshes with the gear 1211a. As the gear 1211a rotates counterclockwise, the rack 1221a can drive the moving part 122 to move away from the rear panel 220 of the cabinet 200 along the first direction X.

[0128] Please continue reading Figure 13bAs shown, the third protrusion 123 also moves away from the rear panel 220 of the cabinet 200 along the first direction X with the moving member 122, so that the third protrusion 123 abuts against the second surface 2312 of the second protrusion 231. Since the cabinet 200 remains stationary, the second surface 2312 of the second protrusion 231 can apply a second force to the third protrusion 122, so that the computing device 100 can move toward the rear panel 220 of the cabinet 200 until the first interface 130 on the computing device 100 is plugged into the second interface 221 on the cabinet 200. Figure 13c The computing device 200 is mounted in the cabinet 200. The calculation method for the second force is the same as that for the first force F1, and will not be repeated here.

[0129] By providing a third protrusion 123 and applying a second force during the mounting process of the computing device 100 through abutment between the third protrusion 123 and the second surface 2312 of the second protrusion 231, the protrusion interacting with the cabinet 200 during mounting and the protrusion interacting with the cabinet 200 during unmounting can be separated. This avoids the back-and-forth movement of a protrusion between the first surface 2311 and the second surface 2312 of the second protrusion 231 to accommodate both mounting and unmounting processes. The back-and-forth movement of a protrusion on the moving member 122 between the first surface 2311 and the second surface 2312 of the second protrusion 231 would require the moving member 122 to partially compensate for the gap between the first surface 2311 and the second surface 2312 of the second protrusion 231, increasing the ineffective travel of the moving member 122.

[0130] Figure 14 An exploded view of the first end of the handle in a computing device provided in an embodiment of this application.

[0131] See Figure 13b , Figure 13c and Figure 14 As shown, a hook 1212 is provided on one side of the first end 121a of the handle 121. One end of the hook 1212 has a locking part 1212a. When the computing device 100 is mounted in the cabinet 200, the first end 121a of the handle 121 rotates to be close to the bottom wall 111 of the housing 110. A locking post 1112 is provided at the edge of the bottom wall 111 of the housing 110. The locking part 1212a of the hook 1212 is locked onto the locking post 1112, so that the first end 121a of the handle 121 can be connected to the housing 110. Thus, the handle 121 can be prevented from rotating relative to the housing 110 when it is not needed to be mounted.

[0132] Please continue reading Figure 14As shown, the first end 121a of the handle 121 has a first through hole 1213, the hook 1212 has a second through hole 1212b, and the cylindrical pin 1214 is inserted into the first through hole 1213 and the second through hole 1212b so that the hook 1212 is rotatably connected to the first end 121a of the handle 121.

[0133] A torsion spring 1215 is also fitted onto the cylindrical pin 1214. One end of the torsion spring 1215 abuts against the periphery of the first through hole 1213, and the other end of the torsion spring 1215 abuts against the periphery of the second through hole 1212b. Thus, the elastic force of the torsion spring 1215 keeps the engaging portion 1212a of the hook 1212 engaged with the locking post 1112. When it is necessary to remove the device, a force is applied to the end of the hook 1212 away from the engaging portion 1212a, causing the hook 1212 to rotate around the cylindrical pin 1214 relative to the first end 121a of the handle 121, thereby disengaging the hook 1212 from the locking post 1112.

[0134] Figure 15 Another schematic diagram of the plug-in / plug-out mechanism in a computing device provided in the embodiments of this application; Figure 16 for Figure 15 The diagram shows the plug-in / plug-out mechanism in the open state. Figure 17 for Figure 16 An explosion diagram.

[0135] See Figures 15 to 17 As shown, the movable member 122 has a first opening 1223 extending along the second direction Y, and a third protrusion 123 is aligned with the first opening 1223 along the second direction Y. The third protrusion 123 can move relative to the first opening 1223 along the second direction Y. When the computing device 100 is mounted, the third protrusion 123 extends from the first opening 1223 to protrude from the side of the movable member 122 away from the elongated portion 1221. When the computing device 100 is removed, the third protrusion 123 retracts relative to the first opening 1223 to be at least flush with the side of the movable member 122 away from the elongated portion 1221.

[0136] During the movement of the movable member 122 relative to the housing 110, the third protrusion 123 and the first opening 1223 are aligned along the second direction X, and the movable member 122 can move relative to the first opening 1223 along the second direction Y. Thus, when the computing device 100 is mounted, the third protrusion 123 can move along the second direction Y to protrude from the elongated portion 1221 on the movable member 122 so that the third protrusion 123 abuts against the second surface 2312 of the second protrusion 231.

[0137] When the computing device 100 is removed from the shelf, the third protrusion 123 moves away from the rear panel 220 of the cabinet 200 along with the computing device 100. Since the third protrusion 123 is located between the rear panel 220 and the second protrusion 231 of the cabinet 200 along the first direction X, the second protrusion 231 will interfere with the third protrusion 123 when the computing device 100 moves away from the rear panel 220 of the cabinet 200 along the first direction X. This will affect the smooth removal of the computing device 100. At this time, a force is applied to the upper edge of the third protrusion 123 along the second direction Y, so that the third protrusion retracts from the first opening 1223 to be flush with the moving part 122, which can avoid the interference between the second protrusion 231 and the third protrusion 123, so that the computing device 200 can be removed from the shelf smoothly.

[0138] Please continue reading Figures 15 to 17 As shown, the insertion and removal mechanism 120 also includes a slider 124. The third protrusion 123 is connected to the slider 124. The slider 124 can move relative to the moving member 122 along the inclined direction D. The inclined direction D is inclined relative to the first direction X and the second direction Y.

[0139] Specifically, the tilt direction D refers to the direction that is tilted relative to both the first direction X and the second direction Y within the plane formed by the first direction X and the second direction Y. For example, the angle between the tilt direction D and both the first direction X and the second direction Y is 45°, or the angle between the tilt direction D and the first direction X is 60° and the angle between the tilt direction D and the second direction Y is 30°. The larger the angle between the tilt direction D and the first direction X, the larger the length component L2 of the slider 124's movement length L1 along the tilt direction D along the second direction Y. Thus, the movement component of the third protrusion 123 along the second direction Y can be satisfied even when the movement length L1 is small. When the angle between the tilt direction D and the first direction X is too large, the size of the base 125 along the second direction Y needs to be set larger, and the space occupied by the base 125 along the second direction Y in the housing 110 is larger. Therefore, the angle between the tilt direction D and the first direction X can be set according to the specific size of the base 125.

[0140] The slider 124 can move along the inclined direction D. The third protrusion 123 is connected to the slider 124. When the slider 124 moves along the inclined direction D, it can also drive the third protrusion 123 to move along the inclined direction D. The moving length L1 of the slider 124 along the inclined direction D has a length component L2 along the second direction Y. Therefore, the third protrusion 123 can move in the second direction Y while the slider 124 moves along the inclined direction D.

[0141] Figure 18 This is a structural schematic diagram of a slider in a computing device provided in an embodiment of this application, at another angle.

[0142] See Figures 15 to 18 As shown, the insertion and removal mechanism 120 also includes a base 125, which is fixedly connected to the housing 110. The gear 1211a and the slider 124 are both located inside the base 125. The second end 121b of the handle 121 is rotatably connected to the base 125. The base 125 has a first slide rail 1251, which extends along the inclined direction D. The side of the slider 124 facing the base 125 has a first groove 1241, which cooperates with the first slide rail 1251.

[0143] The base 125 can be connected to the housing 110 by rivets or by other connection methods. The base 125 includes a base bottom wall 1254 and a base side wall 1255, with the base side wall 1255 connected to the periphery of the base bottom wall 1254. A rotating shaft 1111 can be disposed on the bottom wall 1254 of the base 125, and the second end 121b of the handle 121 is inserted into the rotating shaft 1111, so that the handle 121 is rotatably connected to the base 125. The movable member 122 is also located within the base 125. The base 125 can accommodate the gear 1211a, the slider 124, the movable member 122, and the rotating shaft 1111, so that the insertion and removal mechanism 120 can form a compact module, facilitating the connection of the insertion and removal mechanism 120 to the housing 110. The base 125 has a second opening 1252 on the side facing the housing sidewall 112. The second opening 1252 extends along the first direction X. The first protrusion 1222 and the third protrusion 123 can move along the second opening 1252.

[0144] A first slide rail 1251 is provided on the bottom wall 1254 of the base 125. The first slide rail 1251 can extend along the inclined direction D. When the slider 124 is installed on the base 125, the first groove 1241 on the side of the slider 124 facing the base 125 cooperates with the first slide rail 1251. The first groove 1241 and the first slide rail 1251 form a limiting structure, which allows the slider 124 to move relative to the base 125 along the inclined direction D.

[0145] Figure 19 Another schematic diagram of the plug-in / plug-out mechanism in a computing device provided in the embodiments of this application; Figure 20 for Figure 19 A structural diagram of the upper and middle covers from another angle.

[0146] See Figure 19 and Figure 20 As shown, the insertion and removal mechanism 120 also includes an upper cover 126, which is mounted on the base 125. The upper cover 126 has a second slide rail 1261, which extends in the inclined direction D. The slider 124 has a second groove 1242 on the side facing the upper cover 126, and the second groove 1242 cooperates with the second slide rail 1261.

[0147] The top cover 126 can be placed on the base 125, and the top cover 126 can be connected to the base 125 by fasteners 1262. By placing the top cover 126 on the base 125, it is possible to prevent components such as cables in the computing device 100 from extending into the base 125 and interfering with the engagement between the gear 1211a and the rack 1221a.

[0148] A second slide rail 1261 is provided on the side of the upper cover 126 facing the base 125. The second slide rail 1261 can extend along the inclined direction DD. When the upper cover 126 is placed on the base 125, the second slide rail 1261 of the upper cover 126 cooperates with the second slide groove 1242 on the slider 124, allowing the slider 124 to move along the inclined direction D. Structures restricting the slider 124 along the inclined direction D are provided on both sides of the slider 124 along the third direction Z, which can prevent the movement path of the slider 124 from changing due to the failure of the restricting structure on one side.

[0149] Please continue reading Figure 16 and Figure 17 As shown, the slider 124 has a first connecting portion 1243, and the side of the moving member 122 facing the slider 124 has a second connecting portion 1224. The first connecting portion 1243 is connected to the second connecting portion 1224, and the first connecting portion 1243 can move relative to the second connecting portion 1224 along the second direction Y, so that when the third protrusion 123 moves relative to the moving member 122 along the second direction Y, the slider 124 moves relative to the moving member 122 along the inclined direction D.

[0150] The first connecting part 1243 is connected to the second connecting part 1224, allowing the movable part 122 to connect with the slider 124. By rotating the handle 121, the movable part 122 can move along the first direction X. By connecting the first connecting part 1243 to the second connecting part 1224 and allowing the first connecting part 1243 to move relative to the second connecting part 1224 along the second direction Y, the movable part 122 moves along the first direction X, simultaneously causing the slider 124 to move along the inclined direction D. Simultaneously, the slider 124 moves along the inclined direction D, simultaneously causing the third protrusion 123 to move along the second direction Y. Thus, by driving the handle 121, the movement of the movable part 122 along the first direction X and the movement of the third protrusion 123 along the second direction Y can be achieved simultaneously. In other words, the slider 124 is also driven by the handle 121. The slider 124 and the movable part 122 are driven by the same driving device, making the internal structure of the insertion and removal mechanism 120 simpler.

[0151] The movable member 122 moves along the first direction X, and the slider 124 moves along the inclined direction D. The first connecting part 1243 moves relative to the second connecting part 1224 along the second direction Y, allowing the slider 124 to move relative to the movable member 122 along the second direction Y while simultaneously moving along the inclined direction D. The first connecting part 1243 can be a rotating shaft extending along the second direction Y, and the second connecting part 1224 can be a bushing fitted onto the rotating shaft. When the rotating shaft rotates, the bushing can move relative to the rotating shaft along the second direction Y, allowing the slider 124 to move relative to the movable member 122 along the second direction Y while simultaneously moving along the inclined direction D.

[0152] In one possible implementation, one of the first connecting portion 1243 and the second connecting portion 1224 is a socket extending along the second direction Y, and the other is a column extending along the second direction. The column is inserted into the socket and the column and the socket are fitted with a clearance.

[0153] For example, the first connecting part 1243 can be a socket, and the second connecting part 1224 can be a column; or, for another example, the first connecting part 1243 can be a column, and the second connecting part 1224 can be a socket. Figure 17 In the illustrated embodiment, the first connecting portion 1243 can be a socket, and the second connecting portion 1224 can be a column. The column is inserted into the socket, making it relatively simple to connect the moving member 122 to the slider 124. The clearance fit between the column and the socket can reduce the resistance of the slider 124 moving relative to the moving member 122 in the second direction Y.

[0154] Figure 21 Another schematic diagram of the plug-in / plug-out mechanism in a computing device provided in the embodiments of this application; Figure 22 for Figure 21 Another state diagram.

[0155] See Figure 21 and Figure 22 As shown, the insertion and removal mechanism 120 also includes an elastic element 127. The base 125 has a partition 1253. The gear 1211a and the slider 124 are located on opposite sides of the partition 1253. One end of the elastic element 127 abuts against the partition 1253, and the other end of the elastic element 127 abuts against the slider 124.

[0156] The elastic element 127 can be an elastic sleeve or a coil spring. Figure 21 In the embodiment shown, the elastic element 127 is a helical spring. Please continue reading... Figure 17As shown, the slider 124 has a mounting hole 1244 extending along the inclined direction D. The mounting hole 1244 is open at one end facing the partition 1253, and closed at the other end facing away from the partition 1253. The elastic member 127 is partially located in the mounting hole 1244, such that the elastic force direction of the elastic member 127 is consistent with the inclined direction D. One end of the elastic member 127 along the elastic force direction abuts against the partition 1253, and the other end extends into the mounting hole 1244 and abuts against the end of the slider 124 facing away from the partition 1253.

[0157] Under the elastic force of the elastic member 127, the distance between the slider 124 and the partition 1253 is maximized. As a result, the third protrusion 123 connected to the slider 124 is kept flush with the side of the moving member 122 that is away from the elongated part 1221. Thus, interference between the third protrusion 123 and the second protrusion 231 can be avoided during the process of inserting the computing device 100 into or removing it from the cabinet 200.
